Instantly Translate a Page Using Google's Translation API
You can add the Google Translate web-part to any page. It will leverage Google's translation algorithm to translate all HTML content on the page into whatever language the user has selected from 20+ languages in the Google Translate drop-down menu.
This is great for "quick and dirty" translation, but do not be surprised if the translation lacks quality.
Although it is one of the best free translation engines on web, Google Translate's ability to provide ad hoc translations is still limited because there is no human brain available to consider the context of the words being translated.
As long as you aren't sharing a legal document or other content for which there is zero room for error, this is not a bad component to include for multilingual users.
